Some authors suggest that “an approximation as agreed upon society” must be applied when ethical principles are not available [1]}. Conitzer et al. [2]} discuss a game theoretic and a machine learning approach to the development of a general framework, instead of appealing to the use of ad-hoc rules at each scenario. Furthemore, it would also be convenient to automatize the decision-making process, aggregating the diverse opinions held in the society on ethical dilemmas [3]}[2]}. In this sense, Rossi et al. [5]} discuss related problems where preferences (not necessarily on moral issues) are aggregated by morally-ranking all the alternatives.
